Parents of Marie Martin, wife of Francois Dubuc or Dubuque?

I'm trying to locate the parents' names of Marie Martin who was married to Francois Dubuc/Dubuque on Sep. 5, 1852 in Tilbury, Kent Co. at St. Pierre. Marie's marriage record does not list the names of her parents (or Francois's parents either). Marie was buried at Immaculate Conception in Pain Court, Kent Co. on Aug. 13, 1872. Based on her age in the burial record, she should have been born about Feb. 1822. I don't know where she was born. Oddly, it seems that Marie and Francois had 3 girls born before their marriage in Pain Court (Marianne, Angeline and Marance) and it looks as if they were born in Niagara (don't have any more specifics). Marie and Francois's son Francois died in 1912 in Kent Co. and he lists his mother's birthplace as Niagara Falls (don't if they meant Canada or USA). Any help would be greatly appreciated!!!!!
